Absolutely! You'll just want to do Adjustments for each character.

Alternatively, if you have a webdkp data file, I can look into building an importer for that, if you're willing to wait a few days to a week.

But the fastest solution will unquestionably be to do adjustments for each character to establish an initial standing.

doing adjustments for each character sounds good but when i look at the current standings there are no characters listed on it to do adjustments to and yes i can wait a few days in order for you to build an importer for it

Just click "Show All" in the upper right corner. It's hiding characters that haven't raided recently. Once you get some raid attendance in there, the characters will show properly.

About the importer, if you could upload the file to this thread I can use your data to build the importer.
