You can trade faster, by holding down jump and spamming shift and left click after clicking on the trade, but if you're talking about the inconvenience of going back to the converter every time we have to compress any given ore/material, you're gonna have to wait until next season i believe to get those features.
In the next season, on the topic of converting ores/materials, there would be 2 Major updates:-
1) A crystal effect on your pickaxe which makes converts any ore mined to its compressed form.
2) a possible /converter command to make the coverter accessable everywhere.
