It is easily possible to create your own collection by following these steps:
On your Shopify admin panel, click on the “Create new bundle” button.
Then choose the “Collection Mix and Match” type of bundling from the options.
َAfter that click on the “Add collection” button.
Then choose the “Create a collection” option.
Now you can choose the products for your collection.
And give a name to your collection. Let's name it "Test 2".
Your collection is shown as see below. Remember that in order to create Collection Mix and Match bundle or save your temporarily made collections, you need to make or select at least two collections and create a collection mix-and-match bundle.
After creating at least two collections, you can make your bundle by pressing "Save".
