Dynamic Object

I agree with SvetaG to go ahead and try out Mr_Bro 's suggestion. However, I don't think it's that much time savings because you will still have to delete all the extra name mappings and you will still have to go through all of your scripts and delete all the old name mappings if one of your goals was to have a cleaned up NameMap. Additionally, both my solution and Mr_Bro 's solution both take advantage of the wildcard (*) character. However, Mr_Bro 's solution is probably like Marsha said, the cleaner way to solve the problem. 

I'm pretty sure that, after you use Mr_Bros solution or my solution, any time you click that UI button (UI object) in the future, it will use the alias with the asterisk (wildcard, *) and stop making new aliases. If your goal was to have only one Alias in the NameMapping for that UI object, (unless I'm missing something), then, since you already generated some aliases for that object that you didn't want to create, you will still have to delete all those extra aliases that you already created but didn't want in the name mapping and then go into the tests which use those aliases and delete the  reference to those junk aliases in the tests.
