Use of cluster with Shapediver

We have big grasshopper files with very complex definitions inside
I’d like to use cluster to simplify the code and maybe create my own collection of cluster to be used in differents SD files
I have heard that cluster can impact performance on Shapediver platform?
Do you have any tips/recommandations about cluster?

Is there a way to explode all clusters in one clic before importing gh file into shapediver ?
Or, is it possible to import the GH file and his clusters ?

Thanks
