Arbitrary waveform generation using timer DMA-burst feature: what is the callback when DMA transfer is complete/half complete?

I am expecting there must be a similar callback function like HAL_UART_TxCpltCallback, HAL_UART_TxHalfCpltCallback in case of using UARTs when using DMA-burst for generating arbitrary waveforms with PWM in order to be able to update the memory buffer...
