Microservices priority, Blocked Request (Redirect URL)

Hi,
please, I have two little questions about microservices (BIG-IP / WAF / ASM)

for example:

Policy: 

WAF-TEST.xyz

Contain microservices (both transparent-mode):

*.test.xyz/*

*.dev.test.xyz/*

1.Q: When I have definied separe microservice: dev.test.xyz , it will work? Or it will take the settings from microservice: test.xyz ?

2.Q: Currently I would like to turn on blocking on dev and set the redirect url (blocking responses), but I can't find that there is a different blocking page for a different microservices.

Is it even possible?

e.g.

https://www.test.xyz/block_pg.php?support_id= <%TS.request.ID()%>

https://www.dev.test.xyz/block_pg.php?support_id= <%TS.request.ID()%>

thank you very much for any advice!
