Custom definitions for kanji

Any plans on letting users add their own definitions for kanji? Or re-arranging the order of definitions?

I thought it would be a good idea to learn kanji alongside new vocabulary, so I mostly use Custom Reviews for new kanji.
For example, I recently learned 改札 (kaisatsu, or "ticket gate")

Issue is, the definitions for 改 don't have kaisatsu, and 札 has kaisatsu as the 2nd definition.
