Specifying options like in CLI? Alternative workarounds

[DEV-ONI]

Thanks for making this project!
I'm currently using this module on a webserver, and was wondering if there was a way to specify directories such as in the CLI:

-Ldirectory / -L directory: Prepend directory to the search list for modules. If this option is used then no builtin search list is used. See the section on modules below

Im unsure if there's a way to do that through this module, but was wondering if there were any alternatives. I was hoping to specify my functions in a .jq module in my project's directory. How do you normally handle custom functions in your projects?
