Mapped object - use wildcard on Index

I have an issue where in our product pop up object (messages, warning windows ETC) receive different Index value between runs and appearances 

I want to refrain from mapping the same object multiple times with different Index numbers, 

I want to be able to look for object with any Index value, Is it possible to set Index value as wildcard (Couldn't use "*")?

any other solution?

How it looks in NameMapping:

Thanks!
