Team Cache separate updates?

[ArmySGT.]

Digging up a 2 meter by 2 meter cube and replacing it quickly with a completely new and loaded 2 meter by 2 meter cube.

Seems reasonably easy to me and with how many are positioned off routes near a geolocation marker relatively simple to do so with not so much deception.

So Teams are buried over time in 3rd canon the Boltholes were unearthed and team equipment plus vehicles were updated.

With this in mind, how would you go about updating cache contents? What would you insert? Would you increase the size or the number of caches? Would you give the Team a cache packing list in their bolthole for each cache?
