Updating Substitution Variables using a Business Rule

Summary

Trying to update the substitution variables using groovy rule

Content

Hi,

I'm developing a pbcs application that has a great amout of substitution variables. I was woundering if there is a way to update all of them using maybe a groovy rule since it is toilsome for the client to update them manually.

I know that on premise I could do it using maxl but how can i do it on pbcs? Any help would be appreciated.

Thanks in advance
