HolebaseSI - is there a simpler/more efficient way to making logs in HolebaseSI?

I am looking at making some logs in Holebase SI and was wondering if I could get some help with increasing efficiency. We don't do it very often as usually we get the AGS from a contractor, however there are some jobs where would like to create our own logs.

Currently, the only ways I know how to input the data is;

1) manually straight into Holebase SI, or

2) exporting the relevant excel files, inputting the data into each file and then importing them back in separately.

Both methods work but are very time consuming, especially the first method. We were wondering if there is a simpler way of making a log so that all the data can be put onto one spreadsheet and then into HolebaseSI at one time?

Any help would be greatly appreciated.
