Using nrf_drv_ppi_channel_assign() to trigger timer clear task?

Question

I'm trying to be a good camper and stick to published SDK interfaces, but I'm stuck on one point. 
 I want to use the PPI to toggle a GPIO pin AND clear the timer on a timer CC event. So I have something like:

uint32_t cc0_eep = nrf_drv_timer_compare_event_address_get(&m_timer, NRF_TIMER_CC_CHANNEL0);

err_code = nrf_drv_ppi_channel_assign(&ppi_channel, cc0_eep, nrfx_gpiote_set_task_addr_get(pin));
APP_ERROR_CHECK(err_code);

err_code = nrf_drv_ppi_channel_fork_assign(&ppi_channel, cc0_eep, nrfx_timer_clear_task_addr_get(&m_timer)); // this is wrong
APP_ERROR_CHECK(err_code);

My confusion is that there is no function "nrfx_timer_clear_task_addr_get()". What's the right argument to pass here? 
 (Related, but less critical: is it possible to mix calls to shortcuts and regular nrf_drv_ppi_channel_assign()? If so, how?)

I think i've answered my own question, but let me know if this is incorrect! 
 uint32_t cc0_eep = nrf_drv_timer_compare_event_address_get(&m_timer, 
 NRF_TIMER_CC_CHANNEL0);

err_code = nrf_drv_ppi_channel_assign(&ppi_channel, 
 cc0_eep, 
 nrfx_gpiote_set_task_addr_get(pin));
APP_ERROR_CHECK(err_code);

err_code = nrf_drv_ppi_channel_fork_assign(&ppi_channel, 
 cc0_eep, 
 nrfx_timer_task_address_get(&m_timer,
 NRF_TIMER_TASK_CLEAR));
APP_ERROR_CHECK(err_code); 
 In particular, nfrx_timer_task_addr_get() takes a second argument describing what kind of task to trigger.
