AAM Same Trait key Name but different key Value

Hi,

I'm planning to send same trait key name but with 100+ different trait key value to AAM(onboarded trait). For eg: couponcode="A", couponcode="B" etc.

In this case, do I need to create 100 different trait. or, will it work if I create 1 trait to consider all key values using regex and to take care of this in dynamic manner.

for eg:

couponcode matchesregex   .*

I would like to consider all users those who are eligible for any coupon code. In this case, if i create the above trait expression and create the segment for the same. Will it work?

Any thoughts on this? @shweta_singh @varun_kalra @gaurang-1 @tof_jossic
