Earliest date for auto dividend investment (ASX)

I’m new to Sharesight and currently setting up portfolios, adding holdings that date back to the early 2000s. The auto dividend investment feature is very useful, however I’ve noticed that automatically generated DRP issues go back only as far as 2008, even for those stocks in which we were enrolled in a DRP scheme earlier than that (as early as 2001). Dividend payments, are calculated right back to the original purchase date of the shares.

Is this something inherent to the Sharesight database – that DRP records only go back to 2008?
