In CLM 3.x users had an option to "Request again" an old request, which was useful in two cases:

1. Restart a deployment after failure with all previuos entered information.
   Not need in most cases in CLM 4.6, but some times.
2. Adding a VM with the same basic configuration (Cluster, Network, CPU, RAM, Storage, ...).
   This is very helpful, if later another VM (e.g. Web oder Application Server) with same config/sizing is needed to scale existing environment without getting and re-entering all these informations.

In CLM 4.6 there is not an equivalent option and this is a regression for me and some our users.
