When praying the Divino Afflatu Breviary, how does one anticipate Matins and Lauds? Is it simply by saying Compline, followed by the "Sacrossanctae et individuae", then the "Aperi Domine os meum", and then starting Matins?

Does it make more sense to say the "Aperi Domine" before the first hour said in the day (for instance, Prime) and the "Sacrossanctae" after the last hour said in the day (in this case, Lauds)? Or do those prayers are said always before/after Matins/Compline?
