submit button - default vs custom (Storyline 360)

As a general rule of thumb we generally tend to stick to Storyline's out-of-the-box features, and avoid adding custom features (where possible). This simplifies our course building process and makes our courseware a lot less error prone.

For example, at one point we used custom next/back buttons instead of the out-of-the-box next/back buttons. But discovered that this was not compatible with Storyline's 'review quiz' feature. Custom next/back buttons simply do not work with this feature.

So.. we're now trying to make a decision - whether to use Storyline's default player 'submit' button, or to use a custom 'submit' button. 

Are there any limitations to using a custom 'submit' button? Will this be compatible with other out-of-the-box features? (e.g. review quiz, retry quiz, etc)

I just wanted to put the feelers out so that we can carefully consider our options.
