Do we need to pray 2 rakaat namaaz for every masumeens ziyarat we recite or it’s recommended for only specific ziyarats?

Can we pray one set of 2 rakaat namaaz for one or more ziyarat by combining their niyat: Eg: Ziyarate Waritha, Ashura and Ziyarate Imam Zamana?

It’s not wajib and actually recommended
So you can pray what you wish
