cbopinfo: Need ability to collect only from log volumes which not attached to any pods

Currently we are able to collect the logs from the preserved log PVs which are not attached to any pods during the cbopinfo collect step alone. So if the user presses  [Enter] during the cbopinfo procedure unknowingly, he has to re-run the cbopinfo step and re-initiate log collection and to collect the required logs.

So it would be better if the user can directly enter the log collection from log retention PVs  without entering into log collection procedure.
