Thoughts on a mounting a removeable milk crate?

[Tree]

I've got a RadRover 6 plus with the Rad Rover rear rack on it. I have a milk crate bungied to it - i love the crate and it serves as my "trunk", and it's VERY secure the way i have it corded.

But I'm also realizing it's a pain in the butt to remove the crate and cords and get it back exactly how i like it.

Any with ideas on how to secure the crate to the rack without the cords, yet make it easily removeable at the same time, because there are times I don't want the crate back there.

In my brain, I imagine there's got to be some sort of sliding lockable mount, but i'm not proficient enough in these sort of things to know what I'm looking for, or even if such a thing is reasonable (making sure its mounted securely is important for obvious reasons, not the least of which is that i don't want it falling off with my laptop or what have you in it. )

Thanks for any thoughts, suggestions, ideas, etc.

If it were me, I'd look at a Topeak Quick Track adapter to attach to your crate. Or, you could go with a ready made solution like their own crate that folds down and also has the quick release, like below:

Cascade Manufacturing makes an adapter for Rad racks, but it's pretty expensive. If it were me, I'd buy a Topeak MTX rack, and transfer the track platform to the Rad rack. Links to both are below:

I had the same thoughts on my Mini 4. I secured it with large enough washer and screws into the existing holes on the rack, worked well but still 4 screws to remove.
  I am on the shorter side and swinging my leg over the crate was not fun.
I found this folding one and it has worked out great for keeping it out of my way when not in use, https://www.homedepot.com/p/Clever-Crates-25-l-Collapsible-Milk-Crate-in-Grey-and-Black-8534175-AAU/318505231?g_store=2710&source=shoppingads&locale=en-US&pla&mtc=Shopping-BF-F_Brand-G-Multi-NA-Multi-NA-Feed-PLA_LIA-NA-NA-Catchall_PLA&cm_mmc=Shopping-BF-F_Brand-G-Multi-NA-Multi-NA-Feed-PLA_LIA-NA-NA-Catchall_PLA-71700000014585962-58700001236285396-92700067144412350&gclid=CjwKCAjwx46TBhBhEiwArA_DjIN9OnfFSCTCdN8ajmWoZUjoRhv_NrUlUEbkk7jpCWQabsHQrMbd2xoCIOkQAvD_BwE&gclsrc=aw.ds

I use 4 toe clip straps. Plenty strong and a bit faster removal process than bungies.
