Planned Tasks - more possibilities to set the repetition

Planned Tasks - more possibilities to set the repetition

Hello,
it would be very helpful, if we could set our own period of repetition, ie bimonthly, quarterly, each 6 months, etc.
Tasks can be planned only daily, weekly, monthly or yearly. However, for prospect activities or "stay in touch" activities we need bi-monthly or quarterly, sometime 6 months periods.
Can you please add this in the product plan?
Thank you 
Miroslava
