ignore missing disks assigned to a session

hi,

if you start a session from which a hard drive is missing you get an error...

you can either add the drive to the system or remove the linked disk from that session.

is there a way to ignore these errors as in "ignore" the presence of specific devices ?
suppose i have to swap (non OS) disks regularly i would like to have my session to ignore a mission disk during start up ...

thanks

ps: sessions running under ESXI 5.5
