The scripting flexibility you provide is quite extensive. I set up scripts to do all the data manipulation work (bringing in tables, joins, renaming columns, deleting columns, etc.) This is very helpful because it manually takes a significant amount of time to build decent Spotfire projects. The scripts I have set up make this go much faster. The next part would be bringing in the visualizations for the data. It would be easier to simply copy existing ones from one project to another project, rather than using scripting to rebuild the visualizations.
You didn't allow the "I need this" to say 1 month or 3 months or anything like that. Some folks do actually plan ahead! If I put down "Nice to have", I don't think you will ever do it. So I put "Soon" down.
I don't know how much work this is. For me, it would be very helpful.
