Need Revision Scheme Help

[bruce.buck]

Switching from another PDM system so I'm not quite sure how to make this work in Vault.

We're using Vault Professional 2013.

Redline documents follow this Revision scheme

IR_RL1

IR_RL2

A_RL1

A_RL2

A_RL3

B_RL1

C_RL1

C_RL2

C_RL3

...

where the RL portion can go as high as needed (ex. IR_RL15), and they don't always end at the same number. So I tried to setup this in Vault

Delimiter: _

Primary: Custom scheme (IR, A, B, C...)

Secondary: Custom scheme (RL1, RL2, RL3...)

We need the workflow to work like this:

<Initial Check-In>

IR_RL1 In-Work

IR_RL1 RELEASED

IR_RL2 In-Work

IR_RL2 RELEASED

IR_RL3 In-Work

<User chooses Revise-Bump Primary revision>

A_RL1 In-Work

A_RL1 RELEASED

A_RL2 In-Work

....

The first problem is getting the initial check-in to come in at the SECONDARY revision level. As is, it wants to bring it in as IR. Ok, I can set the revision bump to happen at RELEASED, so that it looks like this:

IR In-Work

IR_RL1 RELEASED

IR_RL1 In-Work

IR_RL2 RELEASED

This obviously won't work. So I can set the bump to happen at both In-Work and RELEASED, but then it does this:

IR In-Work

IR_RL1 RELEASED

IR_RL2 In-Work

IR_RL3 RELEASED

This won't work either. I could just setup the revision scheme to be completely in the Primary portion the revision scheme, but then I have to program in a set number of RL numbers, and then, if the user needs the next LETTER revision, he can just bump it using Revise, he'll have to type in the exact text (A_RL1) to get there.

There's got to be a better way. Any ideas?
