A recent post to the GGA Facebook page asked if there was a bookmark list available of all of the GGA Events. While a bookmark list wasn't available at the time, I did have a GSAK database of all GGA events, which meant I could easily create a GPX file. Now, how to get a GPX file into a List? A quick google search turned up the following instructions (http://www.cach.ly/support/index.php?/topic/1321-gpx-file-imported-into-geocachingcom-list):

1) Use url http://jakuje.dta3.com/gpx2gc.html and choose your GPX file. This tool extracts the GC codes. Copy this list to the clipboard.

2) In Project GC, create a new list in the Virtual GPS. This requires a premium membership. The create list dialog has a place to paste the list of GC codes.

3) Create a new empty bookmark list on geocaching.com as the API offers no way to create a list.

4) Click the checkmark box above the top of all the individual check mark lines. This selects all your caches. I'm not 100% certain you need to do this but play it safe.

5) in the Export dropdown, choose Export to bookmark list and select the new empty list you made and click Export. Presto, your list now has the GCs from the GPX.

You can accomplish the same thing using cachetur.no which won't require a PGC premium membership. Register for a free membership. Then do the following:

1) Use url http://jakuje.dta3.com/gpx2gc.html and choose your GPX file. This tool extracts the GC codes. Copy this list to the clipboard.

2) Choose Create New Trip from the Trips menu. Under the Waypoints tab on the create trip screen, is an Add list of GC-codes. Paste your copied list there. Then switch to the Trip Info tab and fill in the mandatory stuff and Save the Trip.

3) Now that the trip is created, from the Download menu, choose Export to bookmark list (note: you may have to create a new list on geocaching.com before this step) Presto, you now have a list from the GPX. 

Enjoy!
