Hi,
I'll give you a 15 minute solution for yourself. If you find it useful, I'll give you another 15 minute exercise to make it re-usable by others.
Press CTRL+F and choose Common Searches. In the middle drop-down choose Recently Modified Elements.
Now click on the icon that creates a copy of this search and give it a name ( i.e. Recently Modified Requirements).
The query builder should open. If it does not, click on the "Edit Search" icon.
Add a line almost at the end (above the line ORDER BY ), as follows:
AND t_object.Object_Type IN ('Use Case', 'Requirement')
Save the search and enter a number into the search string.
In order to verify that you cover everything you need, change the line to as follows:
AND t_object.Object_Type NOT IN ('Use Case','Requirement').
I just discovered a TYPE of object called Risk, which is probably also considered a requirement, so I will add that to my WHERE clause, as follows.
AND t_object.Object_Type IN ('Use Case', 'Requirement', 'Risk')

P.S. You can limit the search to a specific part of the model, by using the #BRANCH# macro, but that is another advanced topic, so let's not confuse the solution, for now.
