Does deployment solution 7.5 sp1 hotfix 5 support winpe5.1

Hi there,

Can winpe5.1 be imported into deployment solution 7.5 sp1 hotfix 5?  We are currently using winpe4 and I cannot find a way to import winpe5.1 into the preboot configuration settings.  I have downloaded and installed winpe5 on the notification server and then upgraded to winpe5.1 as per the post located on the forums but cannot find a way to import into the preboot configuration settings.   From reading through the forums, I can only find one post dated 2014 stating that winpe5.1 is supported from 7.6 upwards. 

Thanks in advance.
