I needed to be able to clear my reporting services data cache to get accurate loading times for reports. Unfortunately, you have to manually find the .rdl.data files and delete them, or run command line text to clear them. After a little research, I found an awesome tool which not only added a right click -> Delete Report Data Cache, but also added a lot of additional tools in BIDS which I haven’t had the chance to try out yet. Check it out below:

Please let me know if anything it adds is useful!
