3D convolution for Deep Neural Network (DNN) module

Hi all, Is there any plan to support network models which have 3D convolution and 3D Max Pooling? I mean the input to the network is 5D (e.g. "NDHWC" that is: batch-depth-height-width-channel). At now (OpenCV 4.0.0-beta) readNet() function only supports "NHWC" and "NCHW" data format.

I think the support of 3D convolution and 3D Max Pooling would be very important for the community, a lot of volume data (Video, Medical Images, etc.) are processed with this type of CNN. Thanks, L
