Let's Control It

I have built my my marquee control around an ESP-01 running ESP Easy to control the two relais using the two gpios. Things work fine and I've even created a ruleset that automatically drives the marquee to defined points - actually, drives it a defined distance (10%, 25%, 50%, 100%)
Two things I wonder:

• can a rule event take a parameter? (like: event=extend&dist=10) - this would also require that there is some basic math feature (like, multiplying with 4) available
• I have found the command gpio,n,[01] to be available, would pulse also be available in rules?

thanks
