I don't know of a way to fully automate it, but once you have the single vertex stored as a label you could run mri_label2label to do the dilation.

Dear Freesurfer experts,

I am about to start an analysis where we will be drawing surface ROIs using the select_talairach_point option, making a label of the vertex selected, and dilating it a set number of times. Each subject has 19 ROIs and we have around 50 subjects. I was wondering if anyone knew of a way to use a script to automate this process.

Thanks!
