I am integrating from another CRM/Pipeline management software because GoHighLevel is much more in depth with automations and integrations. However, because I have been in business for 5 years I want to also add in all of my previous closed opportunities so that I can compare data across months and years, not just new sales that I get while a part of GHL (payments happen outside of GHL)

When I add old opportunities that are WON, the date that I add them is the date that they are won, completely messing up my data...

Similarly, if a deal closes on 1/31 but doesn't get marked until 2/1, now the data for January and February are messed up.
