Yes, you can do that, root17.
You'll want to use the class and location tracking to monitor the income and expenses of these two venues. You have the option to use this feature alone or together.
Here's how you can turn these features:
At the upper right corner, click the Gear icon.
Select AccountsandSettings under YourCompany.
From the left menu, choose Advanced.
Click the pencil icon along the Categories section.
You can either check Trackclasses or Tracklocations, or both.
Then, click Save and then Done.
After turning the feature, you can name classes or location as an indication if the transaction is under Shopify or Etsy. For more information you can refer to this article about class and location tracking.
Please let me know if you have other questions about this feature.
