How to customize command line prompt?

Well aware of the 

$PS1
variable of the BASH shell, but what variable or configuration file controls the prompt of TMSH? I would like to make the command prompt of TMSH a bit slimmer - eliminate config-sync status and partition. 

 1) Bash shell, controlled by PS1 variable
[root@localhost:Active] config 

 2) TMSH shell - how do I modify this?
root@(localhost)(cfg-sync Active)(/Common)(tmos)
application delivery
TMOS
TMSH

    Thx to @Jason Rahm and @Mark Crosland.

    Here's the answer if anyone else got the same question:

    tmsh help cli preference, there is a limited amount of stuff to choose from, no shell out to bash for random commands or similar.

root@(d3)(cfg-sync Standalone)(Active)(/Common)(tmos) mod cli preference prompt { 
Options:
  }                     
Values:
  avc-count              fully-qualified-host   mcp-state              user                   
  config-sync-status     host                   multi-line             user-role             
  current-folder         mcp-load-status        status
root@(d3)(cfg-sync Standalone)(Active)(/Common)(tmos) mod cli preference prompt { avc-count host … }

      Thank you :), you saved me from digging in docs 🙂

      I am using this one, hostname is replaced by FQDN and multy-line:

      modify cli preference prompt { user fully-qualified-host config-sync-status status current-folder multi-line }

      I've done some research for an answer, which I've not found, so I figured it would be best to use a thread that's mostly similar to what I am trying to achieve.

       

      I wanted to update the TMSH cli so that all users can see the FQDN of the device in the TMSH parameters. We use TACACS for authentication and authorization.

       

      What I have found is that modifying the CLI prompt in TMSH appears to be a "per user" setting as verified when looking in /config/bigip_user.conf

       

      I am trying to work out if there is a way to modify the CLI such that it applies to all users who login, without having to add a specific entry in the .conf file for each user.

       

      We have a large number of users who access BigIP for various things, and users also come and go as well.

       

      Has anyone achieved something like this?

       

      Thanks.
