Dataset access control

Hi everyone. I require that users can modify a dataset , but I do not want them to be able to add a dataset. Currently , I am having difficulty in getting this organised. I have checked , but I cannot see anything in the documentation about this, or in the community web-site. Can anyone point me in the write direction. Or would the best bet be to create a module , mirrored on the dataset.php, but removes the add dataset button etc.

I have a dataset which contains the companies/people who will visit our company site. I want a controlled user set to be able to update this data set with the information of future visits. However , I only want these users to be able to add/modify data in the dataset.

I then want to run a schedules task to delete old items from the dataset.

Regards

As standard, you can give user groups access to the Dataset option, which will include the Add Dataset option, or no access at all to the Dataset option.

A possible solution would be to add a condition to the code, stating that only Super admins can add a Dataset. This would be a simpler solution to creating a module without the Add Dataset button. You could then give that user group access to the Dataset option in the CMS, but they would not be able to use the button.

Many Thanks.
