Create own template for empty hosted feature service?

[KarstenRank]

Hello,

is it possible to create my own feature layer template in Portal, like the templates provided by ESRI?

Where can I find these templates?

Thanks a lot,

Karsten

Any luck on this Karsten ? I have the same question. Running ArcGIS Enterprise 10.5.
