Yes.
Right click on the Desktop and select Personalize
Select your theme and it will apply
Click on the Desktop Background option at the bottom
Make the changes as required and click Save Changes
The theme will now be marked as Unsaved theme and will retain all the selected theme's settings apart from that which you changed.
You can save this as a new theme if you wish
EDIT: Further answer following comments discussion
To add an RSS feed you will have to manually edit the .theme file
Customise your theme with everything else you want apart from the RSS
Save the theme
It will be located in C:\Users\USERNAME\AppData\Local\Microsoft\Windows\Themes
Open the .theme file in a text editor and update/add a [Slideshow] section as follows:
[Slideshow]
Interval=1800000
Shuffle=1
RssFeed=http://YourFeedURLHere
Save the changes then double-click on the .theme file to reload it into the Personalize settings.
Click on the Download Attachments button when prompted
