Proxy Generator workflow

I'm sure this is possible but am having trouble as sometimes my Proxy Generator App doesn't highlight many available options. I've tried readings the notes and various threads here to no avail.

I have a RAID I'm using as a central hub for a particular project (backed up elsewhere multiple times etc).

I have about 7TB of rushes. I only have about 1TB available space left internally on the editing machine. The RAID is built of spinning disks and I'd much rather work on the local nvme using proxies.

What would the correct workflow be to generate proxies using Proxy Generator on the RAID and then copy them to the desktop/other of the local nvme so that, when the RAID is plugged in, I can toggle back and forth between proxies/original and when the RAID isn't plugged in I can run on proxy only? Ideally I don't want to have to go through and relink things every time.

Edit: I feel this is something to do with the extract tool but despite watching walkthrough videos etc it never shows as an option for me. Anyone care to offer a step by step? The RAID is a TB2 connected by a TB2-3 adapter.

My thinking here is get more storage for the edit system, skip the proxies, and use the external RAID only for backups are archiving.

Probably right but don't think I can fit more nvmes with that mobo (there's a slot but not sure it'll function bandwidth-wise with the gpu).

Could get an 8TB internal nvme but migrating in the middle of edits is a risk I'd like to avoid.

Could assemble a fast pcie card like the sonnet m.2, but I've got a busy month of edits and again, don't need the hassle (nor the cost tbh).

I've got plenty of 4TB external nvmes, don't want to pick up an 8TB for this one edit and add to the pile.

Don't have cashflow for anything like a Thunderblade (at least in a capacity that would seem worthwhile) nor the mental/time capacity to build a cheaper DIY equivalent.

Doesn't need to be NVMe. I use 10+ TB spinners.
