Tasker Task to launch keyboard in number pad style

I'm jus starting to tinker with tasker.. Wanted to create a task tht will launch the keyboard in number pad format.. I use Fleksy which is amazing.. It comes with a number row.. But I cannot switch over to number pad layout like in Google keyboard.. Variable query action has an option to set keyboard type to number/integer which does bring out the number pad version of the keyboard but text editing is limited to the variable query input dialog box.. There is a soft keyboard action which brings up the keyboard but unlike variable query action there is no option to specify tht I want number/integer keyboard type.. Is there something else tht I can do abt it?? My goal is switch from normal alphabetic layout with number row to the number pad layout on a long volume button press when I want to say enter an otp or something
