There is a 100k sats bounty for this feature request. You could:
1) code it yourself
2) find a dev to code it
3) increase the bounty until someone picks it up.
There are other improvements to be made, which improve the experience for all or majority of Damus users.
No worries. There are many apps to choose from. 😏
Damus stores it in the keychain which is much better ux for 99.99% of people
