Hi AJ,
Thank you for contacting us.
It is not currently possible to pre-fill templates, or to upload data into iAuditor templates from a database. You could use a QR Code generator to convert your data into QR codes or barcodes, and then use a Text or Single-Line Text field to scan that code as a faster way of putting pre-set text values into some of your fields. You would also not need to create multiple templates, as you could simply create a new audit, and then scan the relevant code/s to input your data.
If there is anything else that I can assist with, please don't hesitate to let me know.
