Well, if you are a little brave (probably just +2 initiative, it's not too hard):
- Step 0, to back up all console settings if you have any worries about messing stuff up, you can go to Manage > Appliances and hit Export User Settings (gear on the right) just in case something gets messed up. (If it does, "Import User Settings" will wipe all changes and revert to the exported set)
- Download the SavedSearches.zip file from Export Saved Searches
- Extract and edit the XML
- CAREFULLY, VERY CAREFULLY edit the XML down to just the search(es) you want to share. Each search is bounded by "<Topic>" and "</Topic>" tags with the "<name>" tags containing the name of the search. So, delete all the "<Topic>"s with "<Name>" tags that correspond to the defaults, being careful not to delete any "<Group>" tags one layer up
- Save XML to same name
- Re-zip
- Try import again for just those searches.
