Request: Extension fields for a 2da be a separate 2da file

[Finaldeath]

Some 2das get large, quickly, like feats and spells 2das

Having Extension Fields are great but having a way for it to dump them to a separate 2da on export would be amazing. A toggle per-2da under the Extension Fields tab would help me utilise it a fair bit more and not bloat certain 2da files with unnecessary data.
