Hi @paul l101 thank you for posting in the community! Just to confirm my understanding are you referring to the Timeline feature in Lucidspark? 

It sounds like you are trying to use one of our templates could you please share a screenshot of the template or the title of so that I can take a closer look on my end?

Thank you for your help! Please feel free to let me know if you have any questions. 

Yes.  I have a timeline object in my Lucidchart. When I add a milestone object to the timelineI'd like to use a 'field' from my dataset as the date value instead of having a static value.

Hi @paul l101 thank you for following up with that screenshot and description! While it is possible to add data to the Milestone shape to add a header field to the milestone It is unfortunately not possible to use custom data to change the dates associated with the milestone. 

However we're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form? Ideas submitted to this form are passed on to the product development team for their consideration.

Thanks for your request and I apologize for any inconvenience this causes you.
