Can I set feed pause to come on 2 mins before a dosing schedule?

Forgive me if covered elsewhere.
I would like to automate liquid feeding via dosing pumps- I'm not sure how to schedule this:
Firstly at say 8pm a feed pause is to be activated -(which stops return pumps and minimises pumps within tank. Also via program logic it stops & delays on the skimmer, the bit in brackets I know!)
Secondly when the water level has dropped in main tank ( because return pump is off and water level dropping an inch over weir into the sump-taking about 90 seconds) So I therefore want to schedule the dosing to start say 120 seconds after the feed-pause was scheduled.

Can someone help?

I suppose the problem is either how do I schedule a feed pause because if this is possible just do it 2 mins before dosing time
or can you set up a feed pause within a timed event

Why can't you just fix a time for the feedpause AND the dosing.


1 ) you program a timer and use the option 'if active then feedpause'
This will start you feedpause

2 ) minutes later you add you liquid dosing via another timer.

OR

1) you program a timer and use the option 'if active then feedpause'

2) you programlogic Timer X + delayed on => tiggers you dosing
