MOD REQUEST: Disabled Sim Cane Script (Cane removal)

I have a sim I made to resemble my friend who has a cane. I found a cane accessory and it looks really good for the most part however when the sim sits down (like at a computer) the cane stays in their hand and often goes through objects. Ideally there would be a fully functioning cane accessory in the game, but I know that is probably too much to ask.

Therefore, I think it could be pretty simple to make a script mod that when the sim sits down the cane is removed and when they stand again the cane reappears. 

Could anyone do this? Thanks in advance.
