Ddestination nat config gives following options for destination nat rule match conditions :
+ apply-groups Groups from which to inherit configuration data + apply-groups-except Don't inherit configuration data from these groups > destination-address Destination address > destination-address-name Address from address book > destination-port Destination port + protocol IP Protocol + source-address Source address + source-address-name Address/address-set from address book
And none of these are dynamic host names.
However you can try configuring an address book with dynamic host name and then use that address book in destination nat and try.
I have not tried this so not 100 % sure if this will work.
If someone has got a better plan, it would be intersting to know.
