Having selected the portal tool, you can select portal via mouseover.
Once found, the portal will be selected for an update.
In the context menu you can find then an 'UPDATE' option.
For the update you can:
- define own parameters
- paste parameters from other portal (and modify them)
- load parameters from a file (and modify them)
Updating will redraw the portal with active parameters at its original position (at the moment).
