No. (There are filters called [all_inputs] and [all_outputs] but they're not searchable.

I often do a list, so I don't have to repeat the long list, i.e.:

set pci_inputs {PCI_AD* PCI_TRDY PCI_IRDY PCI_CBE*}

Then use that list for all my assignments:

set_input_delay -clock clk_ext -max <value> $pci_inputs

set_input_delay -clock clk_ext -min <value> $pci_inputs

Not exactly what you want, but it might help.
