Add Budget Subtasks and Budget Cost Views

Is there a possibility to implement budget costs into the software? It could function as a subtask but labeled as ‘budget’ instead. For instance, if I create multiple event projects and want to add a budget for each event, I would simply create a budget tag with the ability to itemize the costs (items could function as tags in order to aggregate itemized costs). It would be great to have the ability to get the sum of all inputted budget costs with filters to adjust the desired sum view.
