Creating an incremental custom field

Question

Is it possible to create a numeric custom field with default value that will automatically increment by 1 for each new issue that is created?

And to make it even more fun, can I create a different series of these numbers with an alpha prefix.

For instance, I want to manage customer requirements from several customers in one project and want to issue a unique ID based on the customer.

Field 1 = SRS-1, SRS-2, SRS-3
 Field 2 = TRS-1, TRS-2
 etc.....

These could be in one field where I select the prefix or many fields if needed. (preferred method is one field.)

Also, can these fields be based on the value of a radio button or single select field?

(meaning if I have a previous field that indicates which project is involved, can that affect which serial number field is generated/activated)

Any help on this would be greatly appreciated.

Thanks!

Maybe I'm not being clear.

We have an issue type requirement in project a.

Within that list of requirements we have subgroups of requirements. GeneralReq -1, GeneralReq -2, SizeReq -1, SizeReq -2.

I know that I can create all these requirements and then create a select list for requirement type. GeneralReq, SizeReq, etc.

The problem is that I want each GeneralReq or SizeReq to have a unique ID within the relevant Req subset.  (not using the issue key)

A cascading select will only work for a predefined list, not to create unique IDs.

Er, yes it does, if you populate the select list correctly.  Each option on a select list is unique within the select list, and only searchable on that select list.

In fact, it sounds like a cascading-select might be more use to you, but I'm not sure.

We have within one project several subsets of requirements.  We would like to have unique ID's that begin with a fixed pre-fix that indicates to which requirements subset the issue belongs.

We would want to create a search based on issue where the field is not equal to none to generate the list.  Using a select list does not give us the unique ID.
