Thank you for the quick response! I apologize because I did not clarify that I want to do this in DirectRT rather than MediaLab. I did see that in the manual it notes a !Meta option, and that I can insert a !Meta column that then allows me to do instruct DirectRT to move on to another trial after a certain amount of time, e.g., by putting ">4:30000" to give respondents 30 seconds to complete trial 3 before they are automatically moved on to trial 4. However, I'm unclear where I should position the !Meta column within the DirectRT file. Should it be inserted right after the "trial" column, or at the very end after the "rt:text" column and before the "*"?

Alternatively, I believe I can just specify a style folder that, if I store this in my stim folder, will allow me to update the styles without affecting DirectRT's default style editor. I did a "save as" on the default style file and saved a new version into my stim folder, which I presume I can alter without affecting DirectRT's default style. Additionally, when I created the !Meta column it still wanted me to specify the min/max response in the style editor, so it's possible that I need to do both.

If you could let me know the best series of steps, I'd greatly appreciate it. Thanks in advance.
