It is currently not possible to add specific timeframes to your favorites. However, you can select and customize the default timeframes in the web terminal. To add custom timeframes, follow these steps: 

1. Select the timeframe button. 

2. Scroll down to set up your custom timeframe. 

3. Select the desired value—in this case, 5 minutes and 1 hour. 

4. Save your custom timeframe by pressing the "OK" button. 

These custom timeframes will then appear under the default options.
