Adding additional parameters in HB Vegetation Material

Hi all,

Hope you are doing great. I would like to ask how I can add additional parameters in the Vegetation Material node in HB for green roofs. In the HB Legacy, there is a notepad version of parameters which contain additional parameters. However, in the newer version of HB, the parameters are limited as shown.

Could you please help me with it?

Thank you so much!
