Automation for list

[Lohan]

Hello,
First of all I don't know the exact terms of the software and I apologize for that. I will try to be as explanatory as possible.

I have set up a list for different checklists with different dates depending on the actions to be performed.

Example :
Opening of a residence
start date december 5th 2022

then checklist for the different points for this opening.
Date at 6 months
Date at 3 months
Etc...

I would like to automate these actions which are always the same for 5 or 6 other lists but with dates that change according to the main date.
I could do it manually, but as soon as I try to automate it, it changes my main list too.

Could you help me on this subject.
I can attach (if possible) screenshots of my different points.

Thanks for your help

I think the overarching problem is getting lost in translation, but I can still help with the details.

Look in to Date Variables, and how to do Arithmetic on them.

So you can have Butler add an item "3 months check-in date: {date+12w}" to checklist "To-Do"

If you have different patterns of dates, you could link them to different Butler Rules, triggering when you add a label perhaps, or to a Card Button.

Hope that helps
