A: Hi Waitwhy

We're currently working on the ability to insert slides at the top or bottom of existing presentations w/o an individual new presentation being generated for every line of data.

By doing so you will be able to define a template, an existing (or empty presentation) and then insert the template filled in into that presentation.

I expect this will be available by the end of this quarter!

Thank you for trying SlideFill,
Meg
