Invoking Telephone (Numeric) Keyboard Only in Adobe Acrobat XL Pro

Good Day!

I have been scouring the forum for a while, first time poster, long term wanna be code writer of sorts.  I am trying to create a PDF fillable form for a mileage log, In essence, I am trying to get two separate boxes in a form for mileage and a time, specifically military time.  So I would like there to be a comma in the mileage box (1,234) and nothing for the military time (0830).  Now comes the difficult part, or at least what I find is difficult.  I use this form on my phone, so I am trying to get the tab to invoke or force the telephone keyboard on an IOS device, i.e. 1-9 keyboard only.  I know it is possible because when I switch the format to telephone or zip code, that format prompts for the telephone keyboard on my IOS. 

I only have access to Adobe Acrobat XL Pro.

Please help, I am losing sleep over this...

Thanks in advance for your time.
