It seems Jira Service Desk custom reports only go back 1 year, why would Jira only offer 1 years worth of data when audits can go back 5 years?? We shouldn't have to use Jira Software filters to find historical data. Thanks in advance.
Currently, it's not possible to go back further than a year on the Service Desk reports. We have a feature request suggesting the implementation of this ability:

The workaround, for now, is to do what you are already doing, using filters on Issues and Filters to set the necessary date or the option startofyear("-5").
you can create a custom report from a programatic standpoint using the CLI. Grab the issues through a jql and then go through each issue and grabs its history. Now you have all the data, just write a prgoram to get all the data you need and display it in say a google chart or whatever tool you like
