Thank you for approaching us.
Providing Security and Permissions wrt. to budgets to the tasks is under development and most probably this feature will be available in our next release which will be soon.
Also we are re-designing the structure of Security Permissions with Ganib and will be released in our comming versions.
You can create custom roles of your own and set the security permissions accordingly wrt current module. Please refer below FAQ link for creating and managing custom roles of your own,
Please do share if you have any suggestions about this feature.
Happy Using Ganib!!
