Hi, I would like to call different Site data File using page .Params.

I have data file like:  
foo/category/filename/filename.md  
foo/category/filename2/filename2.md  
foo/category2/filename/filename.md  
foo/category2/filename2/filename2.md

I can call it in type/single.html in partial like:

`{{ $foo := $.Site.Data.foo.category.filename }}`  
and range through it:  
`{{ range $foo }} {{ partial "photo-gallery" . }} {{ end }}`

I would like to customize and call different data file depending on page .Params,  
I figured out that I can customize it like:  
in [page.md](http://page.md) file:  
`myvalue: "filename"`  
and I can call it using:  
`{{ $foo := index $.Site.Data.foo.category Params.myvalue }}`  
and it works  
but I would like to customize in page params category name too, like:  
in [page.ms](http://page.ms) file:  
`myvalue: "category/filename"`

and try call it like:  
`{{ $foo := index $.Site.Data.foo Params.myvalue }}`

how can I achieve it?  
I’m beginner with hugo so I’d be grateful for help 🙂
