Lock mechanism when creating elements

this would be really helpful to have a locking mechanism when creating elements. The use case is the following:

• Application where users can create new elements (e.g. Capex or Projects), for instance using a macro or actions

• The elements should ideally be consecutive numbers. for that purpose a subset returning the max in the dimension is used, and add 1

• Problem: when 2 (or more) users create elements at the very same time, the macro will compute the very same id for both, and only 1 will be created

The idea would be to have a locking mechanism : when an element create call is ongoing, further elements cannot be created. This would make Jedox ACID somehow (especially for the C and the I)
