Would it be possible to add a folder system for sent telegrams?
I have a few telegram templates that I reuse over periods of several months. Given my nations' volume of outgoing telegrams, this means that every time I need to send another copy of a template, I have to go back several dozens of pages in my Sent folder to look up the template code. Even if I click the "Show Mass Telegrams" option, I still have to search through a couple dozen pages, given that many responses to mass telegrams are also classified as "mass telegrams" (see related bug report here).
It would be very helpful if I could create folders where I would put these templates in for easy future look up. I imagine that folders would be useful for many other users, even if not for the same reasons.
If a full folder system is not technically feasible or easy to implement, then some options for outgoing telegram management would still be very useful. For example, there could be an option to assign "tags" to telegrams in the Sent folder (though I imagine that this is technically almost equivalent to having folders). A less flexible but still very useful and likely easier to implement alternative would be to be able to "pin" certain Sent telegrams, for easy future re-use.
