Larger crate capacity

I’m aware that it has been changed from the original 3 slots though I only started playing after the update. However, 5 slots is still rather small for the crates to be viable as storage. Maybe at least 10-15 slots?
I couldn’t find any posts of this nature but constantly running out of space is irritating. For example if I have more than 5 tool items I want to put in a crate, they won’t fit. This also makes scavenging a frustration of no capacity. Maybe an upgrade option alternatively?
