[Feature Request]: Command to keep messages in exports beyond set auto-delete timed conversations window

[cavalrymargarine0x1]

Hi!

I'm not quite sure how to title this ticket.

I have conversations with auto-delete timers set to 4 weeks.

Currently, the way sigtop exports them even with the -i command for incremental, it will "mirror" the conversation, so messages beyond a month from now get erased from the export file as they get deleted from the conversation in Signal, and the newer ones get added to the export.

This feature would be a command that would keep messages in the export file beyond the set auto-delete timer of the conversation even if they disappear from the conversation in Signal

For info I use the text-short format for exporting messages.

I hope this is possible and that this makes sense 😄

Thanks!
