ID for HTML generated messages

[creamteam-de]

Hi, thank you for the module, it's great!.
Currently we are using automatic tests to check our application, and we get the web page elements by ID. We have notice that the html code of the validation messages doesn't contain an ID.
For example:

<bfv-messages _nghost-c4="" ng-reflect-messages="function () { return _this.get">
<span _ngcontent-c4="" class="invalid-feedback" ng-reflect-ng-class="invalid-feedback">This field must be at least 4 characters</span>
</bfv-messages>

Is it any possibility to add an unique ID to "span" element?

Thank you.
