How to change [all[current]fields[]] to [all[current.tests]fields[]]

[Dave]

I have a filter that lists all the fields in the current tiddler: [all[current]fields[]]

Buy what I'd like to get is all the fields of the tiddler named after the current tiddler, but with the suffix ".tests".

E.g. if the current tiddler is "Foo", I want in that tiddler to get a list of fields in the tiddler "Foo.tests"

Is this possible with normal filter syntax?

Thanks,
- Dave

Nevermind, found it:

[all[current]addsuffix[.tests]fields[]]
