# Using Custom Fields
While Tactyc already provides deal tags, sector, geographies and other tracking fields, periodically you may want to create your own custom fields that are internal and specific to your fund. These could be internal status color codes (i.e. "traffic lights"), or any additional information you want to track for investments.
## Creating a Custom Field
From your investments page, click on **Custom Fields**
* Define your custom fields by specifying the name and type. Support field types are:
* Number
* Tags
* Text
* Color Codes
* Dates
* Click **Save** when complete
## **Adding Data to Custom Fields**
After defining custom fields, when you open an investment, a new sector for **Custom Fields** appear in the **Investment Information** section
* Click on **Custom Fields** to open a panel to enter data for the defined fields
* Click **Submit** to enter the data and **Save** the investment
* The investment information section will now show a custom fields section
## **Accessing Custom Fields on the Investments Table**
Custom Fields can also be exposed on the investments table from the **Columns** configuration. These custom field columns can be filtered or sorted to evaluate performance for specific sub-sections of the portfolio.
## Adding Custom Fields to Tearsheets
Custom Fields created can also be added to the tearsheet from the **Customize** dialog. Select desired custom fields and they will be shown on the left sidebar of each tearsheet.
