Any chance in the next update you can also abstract the Tiles in Range Array from the ‘Get Indexes in Range’ and including a local Variable for the ranges that gets cleared and then output to the Find Tiles in Range function? Currently using it to get the range from the current hover tile and set my spell markers, but unfortunately it clears the ‘Tiles in Range Array’ on every lookup. So if it was to output the Range Array instead, I could just use that.
Trying not to touch the Grid Manager as much as possible, and also re-use the functions that you include in it. The deeper I get the more I find little things like this and have to either adjust or make my own functions. 
Hit me up on IM if you have any questions or want me to provide any examples of how/what I am trying to do here and I will be happy to assist!
Edit: Changed the function to look like this;
(Using a Local temporary ‘Struct_Range’ in Get Indexes In Range function)
Working for the interim, but would definitely prefer it be in there by default if possible.
