I find many times, especially when setting people up for the first time on Kashflow, that you need to get live bank feeds initially and then find out where they have imported back to and do a CSV import of the rest. As you need to have "dealt with" all the live bank feeds before you can disconnect the account and import, this becomes difficult to do. Also it is not uncommon to find gaps in the bank feeds which need filling with a CSV import (as I am currently experiencing). The ability to import CSV files whilst still connected would be of major benefit and save lots of time. Quickbooks and FreeAgent both permit this, so it cannot be that difficult to implement.
