Is it possible to invoke a variable procedure name?

Question

Is it possible - within a trigger or elsewhere - to invoke a stored procedure by using a variable containing the name of the procedure?
I would like to be able to use a different procedure depending upon the value in a column of the table to which a row is inserted.
If this is not possible, is there an elegant way to allow for the inclusion of as-yet-unknown record types, which I was hoping to be able to handle simply by adding a new procedure, with the new record type suffixed to its core name. Each such variation would perform some type-specific calculation before invoking a common procedure to do the standard processing.
I feel it ought to be possible but can find no example anywhere in the documentation of a procedure being invoked by anything other than a literal name.
Thanks in advance for any guidance.

SQL> create or replace
  2  procedure p1
  3  is
  4  begin
  5  dbms_output.put_line('P1');
  6  end;
  7  /
Procedure created.
SQL> create or replace
  2  procedure p2
  3  is
  4  begin
  5  dbms_output.put_line('P2');
  6  end;
  7  /
Procedure created.
SQL> create or replace
  2  procedure p3(p_proc_name varchar2)
  3  is
  4  begin
  5  execute immediate 'begin ' || p_proc_name || '; end;';
  6  end;
  7  /
Procedure created.
SQL> set serveroutput on
SQL> execute p3('p1');
P1
PL/SQL procedure successfully completed.
SQL> execute p3('p2');
P2
PL/SQL procedure successfully completed.
SQL> SY.
