Add Images as a font

I want to make my own numbers in Photoshop or Illustrator to be used instead of using a premade font. Other watch face design program have a direct feature to replace premade font with bitmaps and I believe it to be useful in Facer Creator. Some of the workarounds I have discovered here are tedious and end up with unnecessary bloat to the size of the download file.

Thank you for your consideration.

Well, i think this feature would be a very good additition to the Facer Creator as well, but it´s not build in yet as an option.
