Easier way to update ledger

Currently its extremely cumbersome to add entries to ledger. We have to add one by one, which especially is a mammoth task when we have to update a large ledger. It would be great if we can do bulk updates either in the form of
1. Importing CSV of broker statements. This would be the ideal case.
2. Ability to bulk add entries rather than adding entries one by one.
3. Or ability to add entries for a specific date range like quarterly or monthly

Or any other way you guys see fit as long as it doesn’t become like a full time accountant job for me
