Who is in charge of storage?

I recently finished a gig designing costumes for a production at a local theatre, and their costumes/props/set storage areas are such a mess it was difficult to navigate, and a detriment to how the theatre functions. What is the title of a person who manages this type of storage? I'm writing a thank you note right now and want to express my interest if they ever decide to hire someone for this role, and want to sound like I know what I'm talking about. 😂

Update- I sent the letter just as a thank you, not expressing interest in a position that likely doesn't exist. I went in today to finish striking costumes, and spent an extra 2hrs getting other costumes off of the floor at least. I'm doing another show with them in a few months, and plan to hack away more at the mess then.

Thank you all for your input!
