File name in shell command

[bfxfer]

Is there a shortcut to specify the filename in the shell command? Something similar to % in vim.

I use pandoc to convert md files to html, and in vim, I run the following that creates a HTML file from the current Markdown file:

:!pandoc --from=gfm --to=html --output=%.html %

I can do something like below in Helix:

:sh pandoc --from=gfm --to=html --output=<FILENAME>.html <FILENAME>

But, writing every time is tedious. Wondering if there's a way to pass the filename to shell without having to write the filename.
