I have a set of files that I would like to process with a tabularTextDatastore. The content of the files has some specific format (many columns, special encoding, etc.) which is not properly detected by the datastore. Using detectImportOptions and readtable, I am able to load my files in the way that I want. Is there a way to use the 'opts' object that is generated with detectImportOptions as input to the datastore so that I don't have to 'manually' set the relevant Name,Value pairs?

Sounds like you'd like to do the following:

>> opts = detectImportOptions(file,'name',value...);
% Optionally configure various opts.properties 
>> ds=tabularTextDatastore(‘location', opts) 
>> read(ds)

You're right in that currently none of the datastores accept an ImportOptions object. Manually configuring the relevant Name,Value pairs is the suggested approach for now.
