Two or more task deadlines

[Bartosz]

Good morning,
I am a new user of the Trello application, I am trying to implement the application in our company to improve communication. Options for adding comment attachments are great, we only have a problem with the fact that we can only set 1 reminder date. We rent cranes, we would like to set on a timeline, the duration of the contract, e.g. from 01/05/2019 to 31/12/2020, and in the meantime additional tasks that must be carried out, e.g. issuing an invoice to the customer, or looking after the crane up to 10 each month.
Thank you in advance for your help

@Bartosz if you upgrade to Business Class (you can do so on a free trial) you'll have access to advanced checklists which allow you to set due dates on individual checklist items and assign those items to team members:
