Route file name convention support prefix

[BoatNavi8]

I want a prefix for a route dynamic segment.

For example, 'invoices/all:invoicename' for 'invoices/allgood','invoices/allbad','invoices/allfinished'...
And the filename can be ' [all]{$invoicename}' or ' all' perhaps.
invoices
├── [all]{$invoicename}.tsx

For example, 'things/pro:name' for 'things/probook','things/promouse','things/procup'...
And the filename can be ' [pro]{$name}' or ' pro' perhaps.
things
├── [pro]{$name}.tsx

The prefixes are not suitable to be a segment. They are too short or Meaningless.
Suffixes can also be considerated.
