One touch drapery controls?

[Ryan Wright]

Has anyone modified their electric drapes to open and/or close with a
single button press, rather than being forced to stand there and hold
the switch down for what seems like an eternity?

I have a variety of ideas on how this could be accomplished but I'm
hoping there's some off the shelf product I can buy, or basic
instructions to follow, before I try to hack something in myself.
