Thunderbird - open all attachments in dispvm

I have Thunderbird (102.5.1) in fedora-36 (4.1.1), and I’ve enabled the service app-dispvm.thunderbird to open attachments in a dispvm.

I have the option (along with default viewer) to open .jpg with qvm-open-in-dvm.

Is it possible to enable the qvm-open-in-dvm as default for all file types?

Not that I know of. See:

Many thanks @adw

Great to read the thread, and to see it’s something that will (hopefully) be soon.
