I've any action "Click Bold" ( see below 1) , How to add more command from this bold action to automatically drop-down for me the button " 🆂🆂 " ( see (2) )?

so that I can just need to click the drop-down items ( "SR or S+1" ) ( see (3) )

** If I have more drop-down buttons in a row, is it possible to automatically drop-down all these 3 drop-down buttons at the same time ?

Thank you very much.
