Run Simulataneuous... only per macro or system wide

[ilcaa]

i want to change the Macro run command from Ctrl+r to my - num key (much faster to reach and only 1 button)
so i set-up a keyboard shortcut to press CTRL+R with trigger of NumKey -

it works, but with every new macro, i have to select "run macro after" or "run simultaneously".  so my question. can i set this multi-macro runtime system wide (all macros inherit the setting) or is there a better way to re-assign the macro run shortcut.

thanks alot
