GTM Persistence issue- Can we create Irule for this?

hello,

I am configuring GTM as a Active-Active set up for a production environment. Since they are having very sensitive application servers which needs to be accessed from Internet, Can we configure persistence to stick to the same application server from the same source address based on session/cookie persistence method?

I think the default persistence methods won’t help here and can we create an Irule for this?? Any idea?
