I suggest that you should make a list of links of all of your bounties. You can put it on excel or google spreadsheet online. You can also make list of your report on google spreadsheet. And when looking for a bounty have a review on the project, by that you will know if you will continue to report on that project. If you have a good review on a certain project, I suggest you to finish your bounty until the end of their bounty campaign.
Thank u for ur suggestion
