Maybe this may help.
In MassHunter you can change mass peak assignments in each collected spectra. To do this you right-click on spectrum (while you have range select tool enabled) and select "Edit Peak Annotations...". In pop-up window you can change ion species as you like, select ion types and then apply these to the spectrum. I added some screenshots below that were quickly captured from MH Qual B.07.01 SP2.
