>The choice is choosing between another app entirely, not from within options in Telegram.
Thats exactly what you should do. Telegram is not the tool/service that does what you want. It just as much not what you want like Skype isn't what you want and MS Paint is probably also not what you want. Any and all criticism is pointless there is nothing wrong with these tools they just dont do what you wish them to. Leave them to the people who actually want the features that Telegram/Skype/Paint or any other tool provides.
