Yes, MrX.

• In the BookMacster document which contains the items you are looking for, click the tab: Reports > Find/Replace.  A tab will open.  At the top of this tab is an arrangement of several popup menus, called a predicate editor.

• In the second line of the predicate editor, set the first popup to Added.
• Set the second popup to is greater than, which in this case means is later than
• In the third popup, change the date to, whatever, a week ago, or however far back in time you want to search.

Results will appear in a list at the bottom of the window.  To move any or all of them to a more appropriate location,

• Select the item(s) you want to move to a certain location.
• Perform a secondary click (holding down the control key, for example).  A contextual menu will appear.
• In the contextual menu, mouse over Move to ► and then navigate to your desired destination.

Yes, that predicate editor is somewhat wonky and overkill for bookmarks.  If you hold down the option key and click a + button you can go wild creating compound predicates.  But it's a standard control which is built into macOS, so it didn't cost us very much
