There are two ways to recall the last "Import Table Data" settings used.
1) Right-click a table from the Schema Browser and choose "Import Table Data". When you launch import table data that way, it will look up the last used settings for that table.
2) One can find the saved settings for recent imports in the Automation Designer. Open that window and go to the Apps section (default) and then click the "Action Recall" node in the top section (most recent ones are at the bottom of the RHS list). If one want to save an action for permanent re-use, you can copy/paste it out of Action Recall and into another "app".
