Is it possible to only load part of the Rise of the Runelords module?

Good day, I purchased the above module from the marketplace and was wondering if it's possible to only load the parts of the module that I need.  It's bloody huge and given the amount of time it'll take us to progress through it I'd like to shorten the load times and such as my computer gets bogged down by it. I apologize if this isn't the correct forum for this question but it seemed to fit. Thanks.

The only way to do that is to create a game using the module, then delete the parts you don't want.  At a Pro subscription level, you could use the Transmogrifier to take parts out of a game created from the module and use them in another game, which would be another option for keeping the active game small.

If you end upgrade to a pro subscription, my suggestion would be to copy the game.  When you copy, you can select/deselect different categories of things to be included in the copy.  I would copy everything except maps and characters.  Then you would have all the handouts for the AP structure and could use the transmogrifier to bring in the player characters from the original game and maps/npcs as needed.  Since you would have the original to pull from, you could delete any map from your active game if you don't expect to use it again for a few sessions.
