Moneylab has a create your own category feature that allows you to create your own sub-category within any category group (this feature is currently available on the web browser only).
If you are considering using custom categories you might also find transaction Tagging useful. Tagging allows you to define your own Tags and apply those tags to transactions in any category. You can use transaction Tags to analyse your spending across Categories. You might use transaction tags to track things like tax-deductible expenses or the expenses related to a specific project like a home renovation or a holiday.
Create your own category is not currently available in mobile, but we are working hard to make it available in mobile soon, so stay tuned!

You can find the create your own category feature in the Categorise window. Click on the category name of the transaction you wish to change to open the Categorise window.
Before you create your own category, select the Category group that your new category will belong to. In the right-hand section of the window under Subcategory, click on Add Subcategory found under the list of subcategories available for that Category group.
Type in a name for your new category and click the green tick icon to save your new subcategory.
You can also edit or delete any of your own subcategories by selecting the pencil icon (Edit) or selecting the red cross icon (Delete).
To categorise your transaction with your new subcategory, click Save at the bottom right of the window. Our automatic categorisation may identify other similar transactions that you would also like to categorise with your new category. You'll see the number of similar transactions in the bottom left of the window. To categorise all similar transactions with your new subcategory, select the Apply to existing and future similar transactions box at the bottom left of the window before selecting Save.
