Dynamo Script for Title block instance parameter

Hello Everyone,
I new to Dynamo, trying to create a script where I can turn on and off the multiple instance parameters of Title block in one go ( in Dynamo Player I would like to select " Tender issue" from Title Text list, please see attached images). Thank You.

Here is the screen shot of script trying to develop

@gpraj3 In Dynamo 1.x use {“Preliminary Issue”, Tender Issue"}

Are you doing some filtering after selecting the titleblocks?
Otherwise a script is overkill, if you select one titleblock, right click > Select all instances > In entire project you can turn it on / off all of them at once.

Thanks for your replies,
@ salvatoredragotta, I’ll give it a shot with Lists and Dictionaries,
@architectcoding , I am trying to select multiple sheets ( not select all instances), and apply the required stamp on the title block,
soon I’ll let you know how I am going with this one.

If its the same for your model:
Elements have to be titleblocks, not sheets.
Luckily, titleblocks also have sheet number parameter which makes it easy to filter.
