I have a dataimage store and want to noise its images by an external image. However, not use the whole new image, instead use various portions of it

You can use tranform datastore function for this purpose. This allows you to write a custom function specifying how you would like to modify your data.
dsnew = transform(imds, @(inp) custom_fcn(inp, external_image));
