Hi there,  
I’d like to seek advice on strategies around how to setup a common MAP that can be used on different components tag bindings. So in the future I only need to update the common MAP and it applies to all components that uses the same MAP.

On Vision I created a dataset tag where I store all the value/messages and I bind the common tag to Multi-State Indicator \> Styles property. So I can edit the dataset tag and it applies to all Multi-State Indicators with Styles properties bound to this common dataset tag.

What is the best way to do it on Perspective?  
Cheers
