^{Originally posted by Roxas2712 July 25, 2022} Hello,

as I already mentioned I would like to use abacus to log all my purchases etc. remotely :)

therefore it would be great to also label my transactions or add them to a specificity budget directly within the app.

Do you think this would be possible?
