You can add extra subkeys to the same master key. You have to choose the right subkey each time you want to encrypt or sign when you do this.

To add extra subkeys to a PGP key:

Select GnuPG keys from the left side panel.

Select the Personal PGP key from the list.

Right click on the selected key and select PropertiesDetails.

If the Subkeys panel is not expanded, expand it.

Click the Add button to add a new subkey.

Choose the right properties for your key by selecting the appropriate Key Type, Key Length and Expiration Date and click OK.

Always ensure that your subkey expires before your master key since a subkey is useless when its master key has expired.
