No. Once you file on one husband at age 60, you are effectively filing on the other husband. You cannot restrict that application. SSA will decide which is higher and will pay it. You can, however, wait to file on your own record at full retirement age 66ish or even wait until 70 if you apply for widow's benefits before you turn age 62, which is the earliest year to file on your own record. SSA can help you sort this out.
