How to combine in a sentence two verb–preposition pairs that have the same TWO objects?

How could one combine succinctly two verbs with the same two objects with different prepositions? For example, if I can either add gifts to a box and remove gifts from the box, what would be the most natural way of saying that I can do both?

If I would only talk about the gifts, I could say "I can add and remove gifts;" if I would only talk about the box, I could say "I can add to and remove from the box." Now, how can I say both things at once?

"I can add gifts to the box and remove them." That you'd be removing them from the box is implicitly clear. (Nobody prevents you from clarifying by appending a "from there", of course, but you are specifically asking for succinctness.)
