Add KML and/or GPX widgets available?

All,

I would like to provide widgets for our staff to add KMLs and GPX files to our maps. I have found the currently available widgets for adding KMLs and GPX files, but neither will work for us.

The KML widget available will only pull web-hosted KML files. I need it to open files that are saved on a user's computer.

The GPX widget has not been updated in some time and the sample widget is not operating properly.

Can these capabilities be found in another widget?
