Is there a way for me to use a generic "universal remote control" with astro decoder ?

I know there are many cheap astro compatible remote control unit pricing around RM15 or less. But all of them almost look alike in design, and all the numeric keys have alphabets printed together with it which makes the font too small for old people who have poor eye sight.

I am looking for a remote control with huge font on the numeric pad. Better if I can program the remote control to send specific numeric sequence with one key press. The idea is to send for example '708' with one key press.
