My target is to save somewhere multiple "cycles" of selections made by the user.
I mean that the user start to apply data selections, and when it has finished, he click on a button to save this first cycle of selections applied, then start again with the second cycle of selections and so on.
At the end I need to merge all these cycles of selections.
For example, in the first cycle the user selects 'Italy' as Market, then he saves this selection by a button inside a variable var1; then he clears the previous selection made and start with the second cycle, selecting 'France' as Market and again saves it in a second variable var2. at the end I'll merge these two variables to obtain something similar to the string 'Italy, France'
