We had a good request come in from one of our users. What they are looking to do is have certain measure formatting templates set up so that instead of having to hard-code the format for many many measure (ie: #,#.00) it would be possible to set some formatting templates at more of a global or project level. This way I could set all of my numeric fields to use a template called something like DefaultNumber which would be #,#.00 and then if it was decided that we wanted to drop the decimals (or increase the decimals) I could go to one place in the solution, change #,#.00 to just #,# and have this format then be used in all measures that reference it. This would prevent the user from needing to go into LOTS of measures to change things like general number formats or date formats across the solution.
