How to copy the Text across the frames precisely and quickly?

Hi,

I opened an existing GIF format file into RWPaint 2013.1 with 15 frames. I wanted to add the Company Name in the animated GIF, by adding the name in 1st frame by Text tool. But I needed to repeat to add the Name on every frame 15 times. Besides time consuming, I am not sure the location of Company Name precisely on each frame by just dragging the Text by mouse. (Frame 1: x=395 y=458 ; Frame 2: x=397 y=457 ; Frame 3: x=393 y=458 etc)!!!

Please anyone can give me the hand, thanks!
