I'm probably not the only one who's thinking of this, but repeat functions have an annoying delay that somewhat destroys the timing of some games.
For example:
You could want a HUD object to draw multiple images to represent how much health you have, however you need it to be instant so the slot backing for the images render correctly, also this can also be an issue with collision detection as well, especially when scratchers need to have a repeated collision script that works in a pixel by pixel manner.

If the delay was removed (or a new alternate block is made) it would make it much more convenient for the users.
If this could be altered, you'd have my thanks.

You can already do this with custom blocks and “Run Without Screen Refresh” option for them.
