Command line option to open in current directory

Would there be a way to have a shortcut, say a period/dot ('.') after /fp open Mp3tag in the calling/current directory?

e.g.: From within a batch file, call:

"C:\Program Files\Mp3tag\Mp3tag.exe"  /fp:.

Thanks for your time!

Try:
"C:\Program Files\Mp3tag\Mp3tag.exe" /fp:"%cd%"

Worked great, thanks!
