How to mass import rules for opening URLs in specific containers?

[dreirund]

Ahoj,

is there a way to import a ruleset for open-tab-urls-in-specific-container into sidebery?

I have:

• Currently I use the Firefox addon "Containerise" for rules which URLs to open in which firefox container.
• When firefox (re)starts, quite sometimes tab sorting to sidebery tab groups gets messed up: They are moved to other groups (or, mostly, to the second group in my tab groups panel).
• ↗ There is the guess that "Containerise" might be the issue because it messes with tab re-opening.
• I have a lot of rules in "Containerise", which I can export as CSV (and so, also manipulate with shell scripting). It takes the form

  <url> , <container name>
  !<wildcard-pattern> , <container name>
  

  and I want to import that dump into sidebery's open-tabs-in-container ruleset. For manual work it is quite too much (822 entries so far).

Regards!
