[FEATURE] Merging multiple backups together

[anaxonda]

Is your feature request related to a problem? Please describe.
I have whatsapp backups from the same phone number, and from different phones and time periods.

Describe the solution you'd like
It would be great to merge them together to view all chat continuously.

Additional context
I'm inspired to ask this by https://github.com/bepaald/signalbackup-tools that has this capability for Signal backups. In that case the databases are merged before html export. I guess that is a bit tricker (although very useful), but perhaps also the outputted html files can be merged if they match the same contact/conversation?

Hey I am also looking for a similar solution. Have you found a way as yet?

Since multiple users request this feature, I will give a quick response here.

The ability to merge backups seems to me that it is more suitable to be a separate project. However, I'm not entirely closing the door on the idea. There's a chance I might reconsider and incorporate it into the exporter or implement it in a new project in the future. As a result, I'll keep this issue open for until further notice.
