Possibility to add e.g. test/testthat/helper*.R to queried files

[sebffischer]

First of all, thank you for this great package,

I would like to be able to add specific file-patterns, such as ./tests/testthat/helper*.R to the queried files, such that they are listed in LSP references or I can jump to the definitions in those files.

Is that currently possible and if so, how? If not, can it be implemented?

Currently, only the R files under the R directory of a package are automatically indexed. Any other files need to be opened manually in order to for the server to index them. There was a discussion on this issue.
