NWC Form Workflow File Upload 25MB Max Merged

We just launched an NWC Form workflow that is going to save our global Store Design Team significant data entry time! In the past, they have had to upload 2 files to each project site (separate SharePoint location) and then manually fill in the metadata for each file. The problem that we're going to face with our new Nintex solution is that some of the design files are in DWG/DWF (AutoCAD) format and are larger than the 25 MB max imposed by the form settings. Are we able to increase this? If not, are there plans to make this available?
