Simulink.f​indBlocksO​fType for Multiple Types

The function Simulink.findBlocksOfType finds blocks of one type (e.g. 'Mux') in a Simulink subsystem or model. Is there a direct way to find a set of blocks of multiple types (e.g. 'Mux' and 'Demux') in a model? I tried passing a cell array with two values:

blockhandles = Simulink.findBlocksOfType(sys, {'Mux', 'Demux'});

However, this resulted, as was to be expected based on the Simulink.findBlocksOfType help, in an error message:

Error using Simulink.internal.findBlocksOfType

Invalid input for argument 2 (rhs2):

Value must be a character vector or string scalar.

Thus, is there a way to do a single search for multiple block types in the spirit of the attempt above, or do I need to repeat the search for each individual block type?

vdp;
Option=Simulink.FindOptions('RegExp',true);
Simulink.findBlocks('vdp', 'BlockType','Gain|Outport',Option)

I see you're having me look into 'regular expressions' now; every day is a school day. It works well, so thanks!
